Hamilton, from the point at which it was first colonized by settlers, has benefited from its geographical proximity to major land and water transportation routes along the Niagara Peninsula and Lake Ontario. Its strategic importance has created, by Canadian standards, a rich military history which the city preserves.

Tension between maximizing economic growth and minimizing environmental damage was evident, even from the city's early development. The area between Burlington Bay (also known as Hamilton Harbour) and the Niagara Escarpment has been greatly altered for residential, industrial and recreational purposes. Cootes Paradise in Dundas also known as the Dundas Marsh, was a very rich wetland with plenty of fish, birds and other game. Cootes Paradise was named after Captain Thomas Coote, a British army officer of Irish extraction who was stationed in the area at the time of the American revolutionary war in the 18th century. The richness of the valley led to population, and to degradation of the marsh, although its legal protection, starting in the 1880s, and the efforts of civic officials and others, have led to it still being of great environmental importance in the 21st century.

History of Hamilton, Ontario

For about a century after achieving its status as a city in 1846, Hamilton has seen itself in terms of industrial production. It adopted or acquired such nicknames as the Ambitious City, Steel City and the Birmingham of Canada. However, after this period, other sectors of the economy took over and Hamilton became a post-industrial economy but failed to change its image and self-image to match. Here then follows the growth of the Hamilton until the end of the Second World War.

History of Hamilton, Ontario

Prior to colonization, Hamilton was occupied by the Chonnonton, or Attiwandaronk, an Iroquois-speaking nation referred to by French explorers as the "Neutral" people. Since then, there have been successive waves of immigration.

History of Hamilton, Ontario

Pre-1811

Like most of the Americas, the original inhabitants of the Hamilton area were Native North American Aboriginal peoples. The first European to visit what is now Hamilton was probably Étienne Brûlé in 1616. Lasalle also visited the area, a fact commemorated at a park in nearby Burlington.

In pre-colonial times, the Neutral Nation occupied most of the land but were gradually driven out by the Iroquois who were allied with British against the French and their Huron allies. A member of the Iroquois Confederacy provided both the route and name for Mohawk Road on Hamilton Mountain and the route for what would become King Street in the Lower City.

Like British North America itself, the Six Nations confederacy was torn apart by the American Revolution. Indigenous groups loyal to the Crown, under their leader Captain Joseph Brant, were settled in several nearby areas of what became Upper Canada in 1791 and ultimately Ontario in 1867. These included Brant’s Ford (now Brantford) on the Grand River in Brant County south of Hamilton, and Brant’s Block (now Burlington) in Halton County north of Hamilton.

The United Empire Loyalists moved into the Hamilton area during and after the American War of Independence as well, dramatically boosting the population and economic development of the region between the original Upper Canadian capital at Newark (now Niagara-on-the-Lake) and the new one at York (now Toronto). This was to prove crucial, for the fighting between the United States and Britain was not yet over.

Administratively, the whole area was part of the Nassau District, which was renamed the Home District in 1792. Additionally, parts of the area were separately incorporated into the West Riding of York County and First Riding of Lincoln County. In 1798, most of the future Hamilton became part of Niagara District while remaining in Lincoln County.

1812–1844

The town of Hamilton was conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812. Nathaniel Hughson, a property owner to the north, cooperated with George Hamilton to prepare a proposal for a courthouse and jail on Hamilton's property. Hamilton offered the land to the crown for the future site. James Durand, the local Member of the British Legislative Assembly, was empowered by Hughson and Hamilton to sell property holdings which later became the site of the town. As he had been instructed, Durand circulated the offers at York during a session of the Legislative Assembly and a new Gore District was established of which the Hamilton town site was a member. As such, Hamilton's future seemed to be shaped by a private collaboration of Hamilton, Hughson and Durand.
